Despite the initial word that “Hell on Wheels” showrunner, John Shiban would remain with the series for its ten episode third season, Deadline is now reporting that Shiban is also stepping down from his position, leaving “Hell on Wheels” without a showrunner.

Consequently, AMC has reportedly put the renewal of “Hell on Wheels” on hold until a new showrunner is found. What that means for the show’s future or return date isn’t clear. “Hell on Wheels” was a solid performer during its second season on AMC, with an average of 2.4 million viewers without enjoying some of the advantage it had in the first season behind “The Walking Dead.”

Prior to his time on “Hell on Wheels,” Shiban had built an impressive TV career with stints on “The X-Files,” “Supernatural,” “Torchwood: Miracle Day,” “The Lone Gunmen,” “Legend of the Seeker” and “Star Trek: Enterprise.” With that kind of resume, it won’t take Shiban long to find a new project.
